1. Woman with dog. Dog on lead, but still not quite under control as kept on having to yank him back quite violently (poor dog) when kids ran past and he barked with excitement and ran towards them, in one case only just being yanked back before obstructing the running track.
I don't think there's a problem with bringing a well-behaved dog to sports day (held outside of school in a big field). I do think there's a problem with bringing an excitable, badly-behaved one which you're not quite fully in control of. Idiot woman <gavel>
2. Boy with earring has his earring taken off him by irritated teacher. Mum hovered, teacher hands her offending earring and said "X still has his earring in, it's against school rules to wear them in PE or games". Mum says loudly and ostentatiously to X in front of teachers, other parents and other children in class "I'll give it back to you at the next race Love". Undermining, chavtastic behaviour <gavel>
My fantasy was that out of control dog would bite out of control earring woman on the bum. Didn't happen. <sigh>
